    Not necessarily for the tick/highres stuff, but clock events allows
    other users as well to utilize such facilities. We have no users yet,
    but there are drivers, which utilize special timer hardware with nice
    #ifdeffery to allow the driver to be shared. This might be a useful
    thing for such stuff.
